Abstract (en)
A computer-implemented method, system and computer-readable medium for determining an illumination component for a selected point in a multi-dimensional space. The method comprises identifying a set of probes associated with the selected point, the probes located in the multi-dimensional space; for each selected one of the probes, determining which of a plurality of zones for the selected probe contains the selected point and determining visibility of said determined zone from the selected probe; and deriving an illumination component at the selected point by combining scene irradiance data associated with those of the probes from which the corresponding determined zone is determined to be visible. The illumination component being determined may be the diffuse component of global illumination as applicable to computer graphics rendering.
